Weekly Quiz Competition
  • Question 1
    1 / -0
    How do sperms move for fertilization with ova?
    Solution
    Hundreds of millions of sperm vie for a single egg cell. The sperm cells are streamlined in design for this purpose: a long tail to help them move. The tail is called a flagellum, and it uses the energy made by the mitochondria to move the sperm forward. Flagella use a lot of energy, so they're kept dormant until sperm enter the vagina.
  • Question 2
    1 / -0
    The menstrual cycle prepares the uterus for a mature egg. For how long an average menstrual cycle exists in women?
    Solution
    The menstrual cycle is the name for the changes that happen in a woman's body about once a month to prepare itself for a possible pregnancy. During each menstrual cycle, an egg is released from one of the ovaries and the uterus (womb) develops a lining in which a fertilised egg could implant. A menstrual cycle is considered to begin on the first day of a period. The average cycle is 28 days long; however, a cycle can range in length from 21 days to about 35 days.

    So, option 3 is correct.
  • Question 3
    1 / -0
    What happens to the wall of the uterus during menstruation?
    Solution
    If the egg is fertilized by a sperm as it travels down the fallopian tube, then pregnancy occurs. The fertilized egg attaches to the lining of the uterus. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation. So, during menstruation it breaks away and leaves the body through vagina.
  • Question 4
    1 / -0
    Which of the following structures is responsible for providing nutrients to the growing foetus?
    Solution
    The placenta acts to provide oxygen and nutrients to the fetus, whilst removing carbon dioxide and other waste products. In addition, it releases hormones into both the maternal and fetal circulations to affect pregnancy, metabolism, fetal growth, parturition and other functions.
  • Question 5
    1 / -0
    What is taken away by the mother`s blood from the foetus through the placenta?
    Solution
    The placenta acts to provide oxygen and nutrients to the fetus, whilst removing carbon dioxide and other waste products. In addition, it releases hormones into both the maternal and fetal circulations to affect pregnancy, metabolism, fetal growth, parturition and other functions.
  • Question 6
    1 / -0
    Which of the following hormones is not a reproductive hormone?
    Solution
    Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine and thyroxine. They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T₃ and T₄ are partially composed of iodine.
  • Question 7
    1 / -0
    Sperms are stored in which of the following parts of the male reproductive system?
    Solution
    The epididymis is a tube that connects a testicle to a vas deferens in the male reproductive system. It is present in all male reptiles, birds, and mammals. It is a single, narrow, tightly-coiled tube in adult humans, 6 to 7 meters (20 to 23 ft) in length connecting the efferent ducts from the rear of each testicle to its vas deferens and sperms are stored in Epididymis.
  • Question 8
    1 / -0
    Which of the following organs is not a male reproductive organ?
    Solution
    Fallopian tube is the part of female reproductive system where fertilization takes place. These are, also known as oviducts, uterine tubes, or salpinges (singular salpinx) are uterine appendages, lined from inside with ciliated simple columnar epithelium, leading from the ovaries of female mammals into the uterus, via the uterotubal junction.
  • Question 9
    1 / -0
    Egg and sperm fertilize in which part of the female reproductive system?
    Solution
    Egg and sperm fertlizes in the middle part of the fallopian tubes, also known as oviducts. The tube allows passage of the egg from the ovary to the uterus.
  • Question 10
    1 / -0
    What is the normal gestation period for humans?
    Solution
    The average length of human gestation is 280 days, or 40 weeks, from the first day of the woman's last menstrual period. The medical term for the due date is estimated date of confinement (EDC). However, only about four per cent of women actually give birth on their EDC. Mammals during pregnancy can have one or more gestations at the same time for example in a multiple birth.
  • Question 11
    1 / -0
    Which of the following activity is not under the control of nervous system?
  • Question 12
    1 / -0
    How many cerebral hemispheres are present in human brain?
    Solution

    A human brain is divided into two cerebral hemispheres which are covered by the cerebral cortex.

  • Question 13
    1 / -0
    Which of the following is the master gland of the body?
    Solution
    Pituitary gland is the master gland of the body.
  • Question 14
    1 / -0
    Which of the following is related to the central nervous system?
    Solution
    The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord
  • Question 15
    1 / -0
    Which of the following organs is the organ of olfactory receptors?
    Solution
    Nose is the correct option. Olfaction is a chemoreception that forms the sense of smell. Olfaction has many purposes, such as the detection of hazards, pheromones, and food. It integrates with other senses to form the sense of flavour. Olfaction occurs when odorants bind to specific sites on olfactory receptors.
  • Question 16
    1 / -0
    Which of the following receptors are responsible for sight?
    Solution

    `Eyes` is the correct option. Rods are photoreceptors located near the edges of the retina that are responsible for peripheral and night vision.

  • Question 17
    1 / -0

  • Question 18
    1 / -0
